Q:How are steel coils inspected for thickness using ultrasonic testing?: Ultrasonic testing is employed to inspect the thickness of steel coils, utilizing a non-destructive method. When conducting this process, a handheld ultrasonic thickness gauge is utilized to determine the thickness of the coil. The ultrasonic thickness gauge emits high-frequency sound waves that travel through the steel coil. These sound waves rebound from the opposite side of the coil, generating an echo. The time it takes for the echo to return to the gauge is measured and utilized to compute the coil's thickness. The gauge comprises a transducer responsible for emitting the sound waves and a receiver that detects the echoes. To ensure optimal acoustic contact between the transducer and the steel surface, the transducer is placed on the coil's surface, utilizing a coupling gel or oil. The transducer releases a brief burst of sound waves, which penetrate through the steel coil and reach the opposite side. If the sound waves encounter any variations or defects in the coil's thickness, they reflect back to the transducer. These echoes are detected by the receiver, and the time between the emission and reception of the sound waves is measured. By utilizing the known speed of sound in steel, the time taken for the sound waves to traverse the coil and return can be converted into a thickness measurement. This enables an accurate evaluation of the steel coil's thickness at different points. Ultrasonic testing is a dependable and efficient method for inspecting the thickness of steel coils. It permits swift measurements without causing any harm to the material, thereby making it ideal for quality control purposes and ensuring compliance with manufacturing specifications.

Q:I work in a steel foundry 10-12 hours a day where we melt and pour stainless steel tubes. The pour temperature for some of them is very close to the boiling point of stainless steel (about 3800 degrees) because it has to be VERY liquid for the application we use it. Anyway, it does boil a little and we breath in the vapours which I can assure you ARE indeed vapourized stainless steel (it collects and cools on everything and makes a nice shiny coating). Ok, so to the question, does breathing vapourized stainless steel all day pose a health risk such as cancer? Anyone know? I'm just curious.: you okorder

Q:Hi,Well, I live near almost across the street from a forest, and my neighborhood is full of raccoons!!! Recently, I just purchased a bunny and have kept it at my cousin's house for the time being. He has a steel cage, and is about 6 months old. I am considering bringing him home and leaving him in the back yard with his steel cage. I am just afraid that raccoons can bite through the steel and get to him. So the question is... Is is possible for raccoons to bite through steel? Btw,Please don't answer hate comments about me being a bad rabbit owner. I simply want to know if raccoons can bite through steel. If it doesn't work out, the rabbit will stay at my cousins house until further notice. But please, I did not waste 5 points for unneeded answers. Thanksss!: Well the raccoons can't bite through steel unless it is very thin steel, like aluminum foil thickness. But they have long arms and can reach into the cage so that would be my worry. They are also very clever so I don't know if it is safe for the bunny. That would depend upon the size of the cage and how hungry the raccoons are. The raccoons might be tempted to try to steal the bunny's food so that is a concern. Check with a pet shop owner or forester or someone like that who has knowledge about raccoons in the area.

Q:What are the different surface treatments for steel coils?: Steel coils can undergo various surface treatments to achieve different outcomes and applications. Some commonly used treatments include: 1. Hot-dip galvanizing: Steel coils are immersed in molten zinc, which forms a protective layer on the surface. This treatment provides excellent corrosion resistance for outdoor use. 2. Electro-galvanizing: A thin layer of zinc is electroplated onto the steel coils. It offers good corrosion resistance and is suitable for indoor applications. 3. Powder coating: Dry powder is applied to the surface and heated to form a durable coating. It provides excellent corrosion resistance and comes in different colors and finishes. 4. Paint coating: Steel coils can be coated with liquid paint, offering both corrosion resistance and aesthetic appeal. The thickness and finish can be customized according to the desired look and level of protection. 5. Phosphating: Steel coils are immersed in a phosphate solution, creating a thin layer that enhances paint adhesion and improves corrosion resistance. 6. Chromate conversion coating: Steel coils are immersed in a solution containing chromium salts, providing excellent corrosion resistance and acting as a primer for subsequent paint or powder coating. 7. Zinc-nickel plating: A layer of zinc-nickel alloy is electroplated onto the steel coils, offering superior corrosion resistance compared to pure zinc plating and is suitable for demanding environments. These are just a few examples of the many available surface treatments for steel coils. The choice depends on factors such as application, desired corrosion resistance, aesthetic requirements, and budget. It is important to carefully consider project needs and consult with experts to determine the most suitable treatment.

Q:I just bought a used Taurus 85 stainless 38 spl revolver, it's about 25 years old but looks like new. This is my first stainless steel gun. I'm wondering if there's any special things I need to be aware of or cleaning methods? I'm also wondering if stainless steel could rust? in theory stainless means it cannot get stained or rusty. I have a chrome bore AK, cleaning is always super easy, wondering of cleaning a SS revolver would be the same.: Stainless steel WILL rust, but it takes longer. Just think of Stainless as stain less - less, but still present. Clean it as you would any other blued firearm. Keep the same coating of protective oil or preservative lubrican on it as you would a blued gun, and it will look shiny pretty much forever. Stainless steel is not rustproof...it is merely MUCH more forgiving of a harsh world than blued steel. Stainless is not the same as hard chrome. Stainless is STILL steel...so you may have to brush it in places a lot to get the crud out, especially after those thousand-round marathon shooting sessions. But the results are pretty impressive, as you will soon see. Happy shooting!

Q:How are steel coils tested for mechanical properties?: Steel coils are tested for mechanical properties through various methods, including tension testing, hardness testing, and impact testing. Tension testing involves applying force to the coil until it breaks, allowing for the measurement of its strength and elongation. Hardness testing determines the coil's resistance to indentation, providing insight into its overall strength and durability. Impact testing determines the coil's ability to withstand sudden applied loads by subjecting it to a high-velocity impact and measuring its ability to absorb the energy. These tests help ensure that steel coils meet the required mechanical properties for their intended applications.
